This happens because Conda-forge installs an unsupported version of ffmpeg. I have fixed this for fresh installs, but follow the instructions in this post to remedy the issue:

Thanks. I read it and think it's not the same trouble with me. And I try these following actions(conda activate faceswap;conda install -c conda-forge "ffmpeg<5.0" -y )but nothing changed.

Can you provide the latest crash report please ('C:\Users\wsyn4\faceswap\crash_report.2023.12.04.231620149194.log)

[wsyn470]

OK. Thanks.

[torzdf]

Ok, so the ffmpeg downgrade went fine.

Is there a reason that you are using a backup version of the alignments file?

Code: Select all

-al D:/faceswap/LSS/a_alignments_20231130_012544.fsa

You should always be using the file named

Code: Select all

a_alignments.fsa

Unless you have a specific reason to be using an earlier backup, Even then, it is better practice to rename the backup file to the correct name.

Assuming this is an oversight on your part, try with the correct alignments file.

If this still doesn't work, then I will need a copy of:

• a.mkv
• a_alignments.fsa

to investigate further (you can put them on cloud storage and PM me the link)
